WebOverview of two-step synthesis of bromophenacetin from acetaminophen. In this experiment, students will convert the acetaminophen (the active ingredient inTylenol) into phenacetin to exemplify a Williamson ether synthesis. The product will be analyzedby melting point, chemical tests, TLC, and IR and1H NMR spectroscopy. WebInstead of using toxic bromine (Br2) as the brominating agent, a greener process will be utilizing HBr and H2O2. Write a balanced equation for this reaction 2 HBr (aq) + H2O2 (aq) --> Br2 (s) + 2H2o (l) Why is it important to add NaHCO3 slowly to the solution after the bromination is complete? chrysotile chemical formula
